(10) The bent portion K is one in which the end portion of the arc portion E is bent and is hooked on the upper side portion 152a of the connector 150.

The second flat portion L2 serves as a movable shaft when the leaf spring 230 elastically acts to pull the light source unit 100.

The leaf spring 230, together with the connector 150 of the light source unit 100, constitutes the tension mechanism portion 9010 of the lighting device 10. The tension mechanism portion 9010 includes a leaf spring 230 arranged in the instrument body 200 and a connector 150 arranged in the light source unit 100 and pulling the light source unit 100 in the direction of the instrument body 200 by connecting with the leaf spring 230. .. The connector 150 has a plate portion 1501, and the plate portion 1501 has a plate shape and has an opening 152 into which the leaf spring 230 is inserted. A restraining opening 152 is formed.

The number of leaf springs 230 that can be installed can be changed according to the shape of the instrument body 200. When the length of the instrument body 200 in the longitudinal direction is short, the leaf spring 230 may be installed only at one end in the longitudinal direction and the other end may be fixed by a hook or the like. When the length of the instrument body 200 in the longitudinal direction is long, leaf springs 230 may be installed at both ends and the center in the longitudinal direction. When the leaf spring 230 is installed in the central portion, the position where the connector 150 included in the leaf spring 230 and the light source unit 100 corresponding to the leaf spring 230 does not interfere with the power supply device 140 attached to the light source unit 100 is selected.

<Terminal block 240>
A power line connected to an external power source is connected to the terminal block 240. Further, the terminal block 240 is connected to a feed wire that sends electric power or a signal to the adjacent instrument body when the instrument body 200 is connected in the longitudinal direction. Therefore, the power supply electric wire and the feed electric wire are arranged in the recess 211.

<Installation work of light source unit 100>
Next, with reference to FIGS. 12 to 14, the work of attaching the light source unit 100 to the instrument main body 200 pre-attached to the attachment portion 300 such as the ceiling will be described. FIG. 12 shows a state before the light source unit 100 is attached to the instrument main body 200. FIG. 13 is a diagram illustrating a process of attaching the light source unit 100 to the instrument main body 200. FIG. 14 shows a cross section of the light source unit 100 after being attached to the fixture main body 200. FIG. 14A is a cross section taken along the plane with the lateral direction Y as the normal direction, and FIG. 14B is a cross section taken along the plane with the longitudinal direction X as the normal direction. Here, the fixture main body 200 can be attached to the attachment portion 300 by fixing it to a hanging bolt suspended from the ceiling, or directly fixing it to the ceiling with a fixing tool such as a screw.
In FIG. 13,
(A) shows a state before the light source unit 100 is attached to the instrument main body 200.
(B) shows a state in which the tip portion 233 of the light source unit 100 is connected to the connector 150 in a state where the leaf spring 230 is elastically deformed so that the curvature of the arc portion E of the leaf spring 230 becomes large. ..
(C) shows a state in which the back side Ea of the arc portion E slides with respect to the upper side portion 152a of the connector 150.
(D) shows a state in which the light source unit 100 is attached to the instrument main body 200.

(Fig. 13 (a))
In FIG. 13A, in the instrument main body 200, the fixing portion 231 of the leaf spring 230 is fixed to the bottom surface portion 211a by a screw. The light source unit 100 is not attached to the fixture body 200.

(Fig. 13 (b))
Next, in FIG. 13B, the leaf spring 230 is elastically deformed so that the arc portion E is substantially perpendicular to the bottom surface portion 211a with the second flat portion L2 as the center of rotation.
The operator passes the leaf spring 230 through the opening 152 through the tip 233 of the leaf spring 230 for both connectors 150. The operator hooks the tip portion 233 of the leaf spring 230 on the upper side portion 152a of the opening 152 of the connector 150, and suspends the light source unit 100 from the instrument main body 200. This state is a temporary mounting state of the light source unit 100. The two leaf springs 230 are arranged at both ends of the fixture body 200, and the light source unit 100 is suspended by the two leaf springs 230 while maintaining a posture substantially parallel to the fixture body 200.

(Fig. 13 (c))
Next, in FIG. 13C, when the operator grabs the cover side portion 131 and lifts the light source unit 100 to the mounting side (upward), the back surface Ea of the arc portion E of the leaf spring 230 becomes the upper side of the opening 152. It slides on the portion 152a by the restoring force of the spring. The sliding action of the arc portion E of the leaf spring 230 is due to the fact that when the operator lifts the light source unit 100 to the mounting side (upward), the leaf spring 230 tries to return to its original shape by itself. The leaf spring 230 returns to its original shape while sliding with respect to the connector 150 without worrying about the spring 230.

(Fig. 13 (d))
Next, in FIG. 13D, when the operator pushes up the light source unit 100 into the recess 211 of the instrument body 200, the upper end 151 of the connector 150 comes into contact with the bottom surface 211a of the recess 211. At this time, the leaf spring 230 suppresses the sliding of the arc portion E immediately before the mounting of the light source unit 100 on the instrument main body 200 is completed. Then, when the mounting of the light source unit 100 on the instrument body 200 is completed, the arc portion E of the leaf spring 230 presses against the upper side portion 152a of the opening 152 of the connector 150 with respect to the upper side portion 152a of the opening 152. Positioned.
At this time, the spring constant when the leaf spring 230 supports the upper side portion 152a at the inner portion is much larger than the spring constant when the tip portion 233 supports the light source unit 100 in FIG. 13B. This can be roughly estimated as a cantilever beam having the first flat portion L1 as a fixed end because the first flat portion L1 is fixed to the instrument main body 200 in the leaf spring 230. In the leaf spring 230, the linear distance (span) between the first bent portion M1 and the fourth bent portion M4, which is hardly elastically deformed, is, for example, 1/5 of the distance (span) between the first bent portion M1 and the tip portion 233. It is about 1/6. For cantilever beams, the span affects the spring constant by the cube. That is, the spring constant at the fourth bent portion M4 is 125 times the spring constant at the tip portion 233 if it is 1/5, and 216 times the spring constant at the tip portion 233 if it is 1/6. Therefore, when the operator completes pushing (pushing) the light source unit 100 into the recess 211 of the instrument main body 200, the inner portion of the fourth bent portion M4 of the leaf spring 230 is formed in the connector 150 with the opening 152. The upper side portion 152a can be supported. That is, the weight of the light source unit 100 can be supported at the inner portion of the fourth bent portion M4.

<Removal work of light source unit 100>
Next, the work of removing the light source unit 100 from the instrument main body 200 will be described. The work of removing the light source unit 100 is the reverse procedure of the above-mentioned mounting work.
(1) As shown in FIG. 13D, the operator grasps the cover side 131 from the state where the light source unit 100 is attached to the instrument main body 200, and keeps the light source unit 100 in a substantially horizontal state on the irradiation side. Pull down (down).
(2) The operator pulls down the light source unit 100 through FIG. 13 (c) to the state shown in FIG. 13 (b), and removes the tip portion 233 of the leaf spring 230 from the opening 152 of the connector 150.
(3) In the above procedure, the operator removes the light source unit 100 from the instrument main body 200.

The connector 150 is formed with an opening 152 into which the leaf spring 230 is hooked. The upper end of the connector 150 is formed with an upper end portion 151 that abuts on the bottom surface portion 211a that is the bottom of the recess 211 when the light source unit 100 is attached to the instrument main body 200.

<*** Explanation of action and effect ***>
Next, the effects of the first embodiment will be described with reference to FIGS. 15 and 16. FIG. 15 is a diagram showing an engagement relationship between the leaf spring 230 and the connector 150. FIG. 16 is a diagram for supplementing FIG. In the first embodiment, the opening 152 has a trapezoidal shape having a length dimension W1 of the lower side portion 152b and a length dimension W2 of the upper side portion 152a.
The length relationship is
W1> W2
Is.
As shown in FIG. 15, the length dimension W2 of the upper side portion 152a is shorter than the length dimension W1 of the lower side portion 152b. Then, in the first embodiment, the width dimension W3 of the leaf spring 230 is the same dimension from the tip portion 233 to the fixed portion 231. As shown in FIG. 15, the width dimension W3 of the leaf spring 230 is substantially the same as the length dimension W2 of the upper side portion 152a of the opening 152. FIG. 16 is a conceptual diagram for explaining the action and effect. As shown in FIG. 16, when the light source unit 100 is attached to the instrument main body 200, the back surface Ea of the arc portion E of the leaf spring 230 hits the upper side portion 152a. Further, on both sides of the leaf spring 230 in the width direction where the back surface Ea is in contact with the upper side portion 152a, the movement in the lateral direction Y is restricted by a part of the side side portions 152c on both sides connected to the upper side portion 152a of the opening 152. NS.

<Positioning in the short direction>
Therefore, the light source unit 100 in which the connector 150 is arranged is positioned in the lateral direction Y with respect to the instrument main body 200 in which the leaf spring 230 is arranged. Therefore, the light source unit 100 can be mounted on the fixture body 200 with the centers of the fixture body 200 and the light source unit 100 aligned in the lateral direction Y. Further, when it is desired to align the optical axis of the light emitted from the light source unit 100 with the center of the instrument main body 200 in the lateral direction, the optical axis can be easily aligned. Further, since the gaps between the light source unit 100 and the instrument main body 200, which are formed along the longitudinal direction X with the light source unit 100 in between, are substantially the same distance, the balance is maintained and the design is excellent.

<Determining the angle around the longitudinal direction X>
The light source unit 100 is strongly pulled up to the mounting side (upward) in a state where the inner portion of the leaf spring 230 is in close contact with the upper side portion 152a of the opening 152, and is mounted on the instrument main body 200. That is, the bottom surface portion 211a of the appliance main body 200 to which the leaf spring 230 is attached and the power supply attachment surface portion 111b of the plate portion 110 to which the connector 150 is attached are parallel to each other and have an insertion / removal direction Z (FIG. 14). It will be in the normal direction. Therefore, the light source unit 100 can determine the mounting angle 601 (FIG. 14 (b)) of the light source unit 100 around the X-axis when the longitudinal direction X with respect to the fixture main body 200, that is, the longitudinal direction X is regarded as the X-axis. can. Therefore, the light source unit 100 is not attached to the instrument main body 200 at an angle with respect to the longitudinal direction X, and the light emitted from the light source unit 100 can maintain a constant direction. Further, by correctly determining the angle around the longitudinal direction X, the gaps between the light source unit 100 and the instrument main body 200, which are formed along the longitudinal direction X with the light source unit 100 in between, are substantially the same distance. , Because the balance is maintained, it is also excellent in design.

As described above, the connecting tool 150 of the light source unit 100 and the leaf spring 230 of the fixture main body 200, which constitute the tension mechanism portion 9010 of the lighting device 10, are the mounting positions of the light source unit 100 with respect to the fixture main body 200 in the lateral direction Y. Also serves as a position determination mechanism for determining. Further, the connector 150 of the light source unit 100 and the leaf spring 230 of the fixture body 200, which constitute the tension mechanism of the lighting device 10, are angle determining mechanisms for determining the mounting angle of the light source unit 100 with respect to the longitudinal direction X of the fixture body 200. Also serves as.

<Modification example 1>
In FIG. 17, the opening 152 is rectangular, that is, both the upper side portion 152a and the lower side portion 152b have the length dimension W1. Further, the leaf spring 230 has a shape in which the width dimension W4 of the tip portion 233 gradually increases to the width dimension W3 wider than the width dimension W4 toward the fourth bent portion M4. That is, when viewed from the fourth bent portion M4 toward the tip portion 233, the taper-shaped leaf spring 230 gradually narrows in width toward the tip portion 233. The length dimension W1 of the upper side portion 152a is substantially the same as the width dimension W3 of the leaf spring 230, and when the light source unit 100 is attached to the instrument main body 200, the connecting tool 150 and the leaf spring 230 are connected. Is the same as that described in FIG. Therefore, in the case of the modified example 1, the same action and effect as in the case of FIG. 16 can be obtained.

The length dimension W2 of the upper side portion 152a is substantially the same as the width dimension W3 of the leaf spring 230, and when the light source unit 100 is attached to the instrument main body 200, the connecting tool 150 and the leaf spring 230 are connected. Is the same as that described in FIG. Therefore, in the case of the modified example 2, the same effect as in the case of FIG. 16 can be obtained.

<Another variant>
FIG. 19 is a modified example in which the direction of the leaf spring 230 is reversed. That is, in FIG. 11, the tip portions 233 of the two leaf springs 230 face in opposite directions in the longitudinal direction X.
On the other hand, in the case of FIG. 19, the tip portions 233 face each other in the longitudinal direction X. The connector 150 is also arranged according to the orientation of the leaf spring 230. The modified example 3 can be combined with the configuration of FIG. 16, each of the modified example 1 and the modified example 2. In the case of the modified example 3, the same state as described in FIG. 16 is obtained. Therefore, in the case of the modified example 3, the same action and effect as in the case of FIG. 16 can be obtained.

It is a configuration that ensures the position determination in the manual direction Y and the angle determination around the longitudinal direction X.

As shown in FIG. 20, in the appliance main body 200, the fixing portion 231 which is one end of the leaf spring 230 is fixed and the leaf spring 230 is arranged. The instrument body 200 includes a sliding guide 211aa, which is a leaf spring regulating portion 9211aa that regulates the movement of the tip portion 233, which is the other end of the leaf spring 230. In FIG. 20, a pair of sliding guides 211aa are formed on the bottom surface portion 211a, and a gap W5 in the lateral direction Y is formed by the pair of sliding guides 211aa. The length of the gap W5 is substantially the same as the width dimension W4 of the tip portion 233.

As shown in FIG. 21, when the light source unit 100 is attached to the instrument main body 200, the tip portion 233 of the leaf spring 230 is restrained from moving in the lateral direction Y by the gap W5.
Therefore, the state described in FIG. 16 can be further ensured by the pair of sliding guides 211aa.

Embodiment 3.
The third embodiment will be described with reference to FIGS. 22 to 24. In the third embodiment, the tension mechanism portion 9010 including the leaf spring 230 and the connector 150 further has an instrument-side fitting portion 9212. In the third embodiment, the tension mechanism portion 9010 is formed by fitting the upper end portion 151, which is the connecting side fitting portion 9151 of the connector 150, and the appliance side fitting portion 9212 formed on the instrument body 200. Similar to the first embodiment, it has the functions of positioning in the lateral direction Y and determining the angle around the longitudinal direction X.

FIG. 22 shows the connector 150 and the instrument-side fitting portion 9212 of the tension mechanism portion 9010 according to the first embodiment. As shown in FIG. 22, two instrument-side fitting portions 9212 are arranged on the bottom surface portion 211a of the instrument main body 200. The fixture-side fitting portion 9212 is formed by cutting a part of the bottom surface portion 211a in the upward direction Z from the light source unit 100 toward the fixture main body 200 in the insertion / removal direction Z. 23 (a) and 23 (b) are a cross-sectional view showing a state in which the light source unit 100 is attached to the instrument main body 200, and a diagram showing a connector 150, respectively. The cross-sectional shape of the instrument-side fitting portion 9212 is triangular.

In the third embodiment, the fixture-side mounting portion 9200 is a leaf spring 230, and the light source-side mounting portion 9100 is a connector 150 that connects to the leaf spring 230. As shown in FIGS. 22 and 23, the connector 150 includes a plate portion 1501 having a plate shape. The plate portion 1501 has an opening 152 into which the leaf spring 230 is inserted, and is bound to the instrument side fitting portion 9212 by fitting into the instrument side fitting portion 9212 formed in the instrument body 200. It has an upper end portion 151 which is a joint portion 9151.

That is, the fixture-side fitting portion 9212 can be fitted into the upper end portion 151 to determine the positioning of the light source unit 100 in the lateral direction Y and the mounting angle of the light source unit 100 around the longitudinal direction X. In the case of the first embodiment, the back surface Ea of the arc portion E of the leaf spring 230 hits the upper side portion 152a, and both sides of the leaf spring 230 in the width direction where the back surface Ea hits the upper side portion 152a have openings 152. It was necessary that the movement of the lateral side Y was restricted by a part of the side side portions 152c on both sides connected to the upper side portion 152a. However, in the case of the third embodiment, the relationship between the leaf spring 230 and the connector 150 is such that the leaf spring 230 only needs to pull the connector 150. Of course, the movement restriction in the lateral direction Y described in the explanation of FIG. 16 may be added.

FIG. 24 shows a shape in which the upper end portion 151 of the connector 150 and the instrument-side fitting portion 9212 are different from those in FIG. 22. FIG. 24A is a cross-sectional view showing a state in which the light source unit 100 is attached to the instrument main body 200. The cross-sectional shape of the instrument-side fitting portion 9212 is a concave arc shape.
FIG. 24B shows a connector 150 in which the upper end portion 151 has a convex arc shape. In FIG. 24, the convex arc-shaped upper end portion 151 fits into the concave arc-shaped fixture-side fitting portion 9212 to position the light source unit 100 in the lateral direction Y and around the longitudinal direction X of the light source unit 100. The mounting angle can be determined.

Embodiment 4.
The fourth embodiment will be described with reference to FIGS. 25 to 27. 25, 26, and 27 correspond to FIGS. 22, 23, and 24 of the third embodiment. The fourth embodiment is a case where the concave-convex relationship between the instrument-side fitting portion 9212 and the upper end portion 151 is opposite to that of the third embodiment. Even if the unevenness relationship is reversed, the same effect as in the third embodiment can be obtained.

In the first to fourth embodiments, the leaf spring 230 is described as the fixture-side mounting portion 9200, and the connector 150 is described as the light source-side mounting portion 9100. However, in the first to fourth embodiments, the connector 150 may be used as the fixture-side mounting portion 9200, and the leaf spring 230 may be used as the light source-side mounting portion 9100. That is, the connector 150 may be arranged on the instrument main body 200, and the leaf spring 230 may be arranged on the light source unit 100.
In that case, the tension mechanism portion 9010 includes a leaf spring 230 arranged in the light source unit 100 and a connector 150 arranged in the instrument main body 200. The connector 150 pulls the leaf spring 230 in the direction of the instrument body 200.

When the connecting tool 150 is arranged on the instrument main body 200, the connecting tool 150 has an upper end portion 151 which is a connecting side fitting portion 9151 on the plate portion 1501. The tension mechanism portion 9010 composed of the leaf spring 230 and the connecting tool 150 is arranged in the light source unit 100, and is fitted in the upper end portion 151 which is the connecting side fitting portion 9151 to restrain the upper end portion 151. It has 9112. Here, the light source side fitting portion 9112 corresponds to the fixture side fitting portion 9212 shown in FIGS. 22 and 25 formed on the flat surface portion 111 of the plate portion 110 of the light source unit 100. Similar to the case of the instrument-side fitting portion 9212, the uneven relationship with the upper end portion 151 may be such that the upper end portion 151 may have a convex shape or a concave shape.

The central side of the inclined side portion 152d is connected to the lower side portion 152b, and the outside of the inclined side portion 152d is connected to the side side portion 152c. In FIGS. 28 and 29, the inclined side portion 152d and the side side portion 152c are connected via an arc-shaped connecting side portion 152cd, but the present invention is not limited to this form, and the inclined side portion 152d and the inclined side portion 152d are connected. The side side portion 152c may be directly connected to the side side portion 152c without an arc-shaped connecting side portion 152cd.

<*** Explanation of the effect ***>
